A0) ESP8266 input (pin 6). **Check your ESP8266 version**. In earlier chip versions, the A0 pin operated at maximum voltage of 1.0V. Newer versions allow an input voltage in the range between 0 and 3.3 volts. You may need to use a voltage divider to ensure your input voltage is in the right range. ADC0 will be reported in telemetry messages as well as in the web UI. It can also be used as a [trigger](Rules#adc0) in [rules](Rules).

The ESP8266 A0 pin supports a maximum voltage of 1.0V. Many newer Wi-Fi modules have an on-board voltage divider to support a higher A0 input voltage range (typically in the range between 0 and 3.3 volts). You may need to use a an external voltage divider to ensure your input voltage is in the right range.
